CUSTOM RASPBERRY PI INTERFACES - WARREN GAY KAR...

Design and build custom hardware interfaces for the Raspberry Pi and discover low cost display
and sensor options for embedded system projects. With this book you'll master 12C
communications using Raspbian Linux in C++ and perform ADC and DAC experiments. You'll
experiment with debounce buttons and switches using hardware and software solutions. Develop
flywheel rotary encoder effects for ease of tuning and construct a hardware interface to the
Music Playing Daemon (MPD) with developed software. Discover how to add your own hardware
keypad for remote combination lock applications. Custom Raspberry Pi Interfaces offers a
thorough chapter on interfacing 5-volt systems to 3.3-volt Raspberry Pis designed to expand
your choice of peripheral options. Ready to go C++ programs involving GPIO and I2C peripherals
are provided. This book also explores ADC  DAC  rotary encoders  CMOS shift registers. I2C I O
extenders. What you'll learn: Build simple  low cost input output interfaces including rotary
encoders Interface with 5-volt devices from a 3-volt Raspberry Pi system Apply analog to
digital and digital to analog conversions on the Pi Read potentiometers (volume control) from
the Pi Determine step  directions  and velocity of a rotary encoder Perform remote interfacing
using the I2 PCF8574 chip Work with external CMOS devices like the 74HC595 (in C++) Who this
book is for: Students and hobbyists interested in building custom interfaces for their
Raspberry Pis.
